Installation

If you have Cabal-Install installed, the following two commands should install the latest SCC package on your system:

cabal update
cabal install scc

If everything goes well, there should be executable named shsh. On Unix it gets installed in your $HOME/.cabal/bin/ directory by default.

Command-line Shell

To see the options supported by shsh, type shsh --help and you'll get:

Usage: shsh (-c <command> | -f <file> | -i | -s) 
  -c       --command      Execute a single command
  -h       --help         Show help
  -f file  --file=file    Execute commands from a script file
  -i       --interactive  Execute commands interactively
  -s       --stdin        Execute commands from the standard input

Here are a few simple command examples:

Bash + GNU tools shsh
echo "Hello, World!" echo "Hello, World!\n"
wc -c count | show | concatenate
wc -l foreach line then substitute x else suppress end | count | show | concatenate
grep "foo" foreach line having substring "foo" then append "\n" else suppress end
sed "s:foo:bar:" foreach substring "foo" then substitute "bar" end
sed "s:foo:[\\&]:" foreach substring "foo" then prepend "[" | append "]" end
sed "s:foo:[\\&, \\&]:" foreach substring "foo" then id; echo ", "; id end
